[origin: WO9832421A1] There are disclosed ophthalmic compositions having high water-binding properties which are useful as: moisturizing and lubricating (i.e. artificial tear) solutions, dry eye therapies, contact lens wetting and lubricating solutions, and as delivery vehicles for ophthalmic drugs. The subject compositions include glycerin in combination with propylene glycol. The subject compositions may further include cellulose derivatives, e.g. hydroxypropyl methyl cellulose, along with preservatives, e.g. benzylalkonium chloride, PHMB, sorbic acid, etc.. Preferred compositions have at least 11 % bound water, a pH from about 7.1 to 7.5, and an osmolality between about 280 to about 320 mOsm/Kg.
